This Patent Application relates to co-pending applications Ser. No. ______, entitled TOY CONSTRUCTION SYSTEM HAVING A VARIABLE ANGLE JOINT, filed the same date hereof, and Ser. No. ______, entitled TOY CONSTRUCTION SYSTEM HAVING A ROTATABLE CONNECTOR SPINNER DEVICE, filed the same date hereof, both by the same inventor hereof; and the disclosure in each of these co-pending applications are incorporated herein by reference.

FIELD OF THE INVENTION

The present invention generally relates to the field of toy building systems and more particularly to an improved system including a compound connector adaptable for joining a variety of components, thereby enabling the construction of a wide assortment of children's toys and projects.

BACKGROUND OF THE INVENTION

A variety of toy construction systems are available in the market today and described in numerous issued U.S. Patents. Such construction systems commonly have male and female interlocking joints for connecting the various elements together. Although a group of such construction elements can generally be interconnected in a variety of ways, such systems generally have a limitation of the connectors not readily locking in certain orientations, or becoming worn over time, thereby becoming incapable of holding a position at a desired angle.

Exemplary prior art includes U.S. Pat. No. 409,744, entitled TOY BUILDING BLOCKS, which issued Aug. 27, 1889, to A. F. C. Garben. The invention disclosed in this patent relates to building blocks designed for the amusement and instruction of children. The invention includes sphere-headed coupling blocks, which provide a universal joint between pairs of recessed blocks. The result is that any two recessed blocks may be connected in line on a curve or at any angle, and may be held together with sufficient rigidity to make any desired toy structure. A large problem with this invention is that over time the sphere-headed couplings become worn and the objects created will not hold their shape.

Another relevant prior art toy construction system is disclosed in U.S. Pat. Nos. 1,915,835 and 1,916,634, both entitled TOY CONSTRUCTION BLOCK, both of which issued to C. H. PAJEAU on Jun. 27, 1933 and Jul. 4, 1933, respectively. These patents disclose the original “Tinker Toy” building block system, which includes an assortment of relatively inter-fitting elements of varying types that are adapted to be manually assembled into structures and mechanisms of widely varying sizes and types. This invention is somewhat limited in what may be built with the elements.

Still another example of the prior art is disclosed in U.S. Pat. No. 2,622,335, entitled SECTIONAL TOY FIGURE, which issued Dec. 15, 1953 to G. H. Calverley, The disclosed invention relates to sectional toy figures having inter-engagable construction pieces including bodies, heads, limbs, feet and connecting elements. The joints include a socket in the body piece for interconnection with similarly connecting elements. A key problem with this invention is the same as discussed above. Wear on the elements will cause the pieces not to hold their shape.

Yet another prior art example is disclosed in U.S. Pat. No. 3,286,391, entitled CONSTRUCTION TOY HAVING A VARIABLE ANGLE JOINT, which issued to M. Mengeringhausen on Nov. 22, 1966. This patent discloses another joint mechanism for use with toy construction. The invention includes a relatively small spherical connecting member of elastic material having a plurality of substantially cylindrical holes. Again, a key problem with this invention is the same as discussed above. Wear on the elements will cause the pieces not to hold their shape.

Another example of the prior art is disclosed in U.S. Pat. No. 3,458,949, entitled CONSTRUCTION SET, which issued to G. G. Young on Aug. 5, 1969. This patent discloses a terminal unit of spherical shape including a pair of like interlocking members, each having a plurality of circumferential grooves in it. The side walls of each groove, intermediate the ends of the groove, have transversely opposite cavities which form a ball receiving socket. The construction set disclosed in this patent is somewhat limited in what may be constructed.

Many other examples of the prior art are illustrated in issued such U.S. Patents as U.S. Pat. No. 3,510,979, entitled ASSEMBLY KIT, which issued May 12, 1970 to A. Fischer; U.S. Pat. No. 3,747,261, entitled BALL AND ROD LINKAGE FOR JOINING POLYHEDRAL MEMBERS, which issued Jul. 24, 1973 to Nast Salem; U.S. Pat. No. 4,037,978, entitled RESILIENT SWIVEL CONNECTOR, which issued Jul. 26, 1977 to Brian W. Connelly; U.S. Pat. No. 4,078,328, entitled CONSTRUCTION TOY SET, which issued Mar. 14, 1978 to Larry W. Rayment; U.S. Pat. No. 5,897,417, entitled CONSTRUCTION SYSTEM, which issued Apr. 27, 1999 to Michael J. Grey; and, U.S. Pat. No. 6,264,522 B1, entitled CONSTRUCTION SYSTEM, which issued Jul. 24, 2001 to Marilyn M. Dickson. Another prior art toy construction system of interest is disclosed in U.S. Pat. No. 3,648,404, entitled CONNECTOR UNIT HAVING RADIAL ARMS FOR STRAIGHT OR ANGULAR CONNECTIONS, which issued Mar. 14, 1972, to Charles Ogsbury and Don Witte.

DETAILED DESCRIPTION OF ONE EMBODIMENT

Referring now to the drawings and to FIG. 1A in particular, a perspective view of an imaginary child's space fantasy structure 10 is shown. The structure 10 may be assembled from a variety of elements of the toy construction system. First a base plate 11 is assembled from a variety of panels 12 that interlock by means of mating slots 13 and wedges 14. That is, one of the wedges 14 will mate up with a corresponding slot 13 of a neighboring panel 12 in order to lock the panels together.

A rotatable device 20, which is further described in detail in my co-pending application entitled TOY CONSTRUCTION SYSTEM HAVING A ROTATABLE CONNECTOR SPINNER DEVICE (Ser. No. ______), is attached to the base plate 12 with a twist-lock connector 21. The device 20 as amplified in the referenced co-pending application is fixable in a chosen position, which may be altered by a rotation force overcoming the bias between the top and bottom parts thereof. A flexible connector 22, as further described in my co-pending application entitled TOY CONSTRUCTION SYSTEM HAVING A VARIABLE ANGLE JOINT (Serial No. ______), is attached atop the spinner device 20 by means of a twist-lock connection (not shown). The other side of the connector 22 is coupled to one end of a dowel 24 also by means of a twist-lock connector. The other end of the dowel 24 is coupled to one leg of a triple axis compound connector 26 by means of another twist-lock connector.

Connecting to one (i.e., horizontal) axis of the connector 26 is another dowel 28 by means of yet another twist-lock connector. The second end of the dowel 28 is coupled to another spinner device 30 by means of still another twist-lock connector (not shown). The fantasy structure 10 may be enhanced by the addition of a sphere 32 to the opposite side of the device 30 by means of a flexible connector 34. It is pointed out that the flexible connector 34 is amplified in greater detail in my co-pending application entitled TOY CONSTRUCTION SYSTEM HAVING A VARIABLE ANGLE JOINT, and includes both a ball connector and a socket therefor. The connector 34 is coupled to the device 30 and the sphere 32 by means of twist-lock connectors (not shown).

In a similar manner, a dowel 36 is connected along another horizontal axis of the connector 26 (orthogonal to the first horizontal axis) by means of yet another twist-lock connector. The second end of the dowel 36 is coupled to yet another spinner device 38 by means of still another twist-lock connector (not shown). The fantasy structure 10 may be enhanced by the addition of a sphere 40 to the opposite side of the device 38 by means of a flexible connector 42. The connector 42 is coupled to the device 38 and the sphere 40 by means of twist-lock connectors (not shown).

Another dowel 44 is connected along yet another horizontal axis of the connector 26 (orthogonal to the second horizontal axis and coincidental with the first axis) by means of yet another twist-lock connector. The second end of the dowel 44 is coupled to still another spinner device 46 by means of another twist-lock connector (not shown). The fantasy structure 10 may be enhanced by the addition of a star-shaped thingy 48 coupled to the other side of the device 46 by means of a flexible connector 50, a dowel 54 and a compound connector 52 by means of twist-lock connectors (not shown). Additional star-shaped parts 47 and 49 may be connected to the compound connector 52 by means of dowels 51 and 53 connected through flexible connectors 55 and 57.

Still another dowel 56 is connected along yet another horizontal axis of the connector 26 (orthogonal to the first horizontal axis and coincidental with the second axis) by means of yet another twist-lock connector. The second end of the dowel 56 is coupled to still another spinner device 58 by means of another twist-lock connector (not shown). Coupled to the second side of the device 58 is a two-axis compound connector 60, which may be used to enhance the fantasy structure 10 by the addition of star-shaped parts 62, 64 and 66 by means of a flexible connectors 68, 70 and 72, respectively, and dowels 74, 76, and 78, respectively by means of twist-lock connectors (not shown).

Another dowel 80 may be coupled vertically from the compound connector 26 (opposite the dowel 24), which may then be coupled to another spinner device 82 by means of twist-lock connectors. On the opposite side of the spinner device 82 a pivot head device 84 may be coupled by means of a twist-lock connector. A flexible connector 86 may be coupled to the pivot head device 84 and to one end of a dowel 88. The second end of the dowel 88 may be coupled to a flexible connector 90 by means of a twist-lock connector, which in turn may be connected to a spherical compound block 92.

Accordingly, it may be seen that a fantasy space device may be constructed from a variety of disparate elements of the toy construction system of the present invention.

Referring now to FIG. 1B, a perspective view of a child's imaginary space station 100 assembled with the novel elements of the present invention is shown. The structure 100 may be assembled from a variety of elements of the toy construction system. First a base plate 101 is assembled from a variety of panels 12 that interlock by means of mating slots 13 and wedges 14.
